Ok, downloaded the 5.2RC2-i386-miniinst.iso, no luck.
BIOS has an option of
"PCI IRQs to IO-APIC Mapping"  (enabled/disabled)
I didn't see anything else relating to APIC, or APCI(?)

I set that to disabled.  No luck, Then I left it disabled and tried install
w/o apic, still no luck.  Then I ran with logging and have the following
messages on screen after the Waiting 15 seconds....

I know the RAID works, I ran through enough of the Netware6 install for it
to be ready to partition the drives without any problem. 
I can't really try the card in another slot, its being used as a zero
channel raid card for the onboard scsi.  I followed the instructions on bios
settings from intel's site (it's a NA440bx MB  512MB ram, dual P3-600s, no
other drive adapters, CD runs off built-in IDE) During the SCSI card bootup
it reports being at BUS 0, slot 12, irq 11

I'll be glad to provide any other information that might help figure this
out.

Thanks,
Mike
